Lisa took a deep breath, opened her mouth, and immediately pushed forward, trying to swallow his cock whole, lips stretched tight around his shaft as it quickly hit the back of her throat.

*GACK*

“Lisa!” Lincoln exclaimed, grabbing her shoulders and pushing her back.

Lisa coughed, eyes watering, but quickly recovered. “Why did you stop me? I had thought we had already reached the level of trust needed to proceed.”

“I trust you, but that doesn’t mean I trust you to never make a mistake,” Lincoln said. “Now, where did you learn… that?” Truthfully, he was still a bit torn on the idea of letting his younger sister perform this ‘experiment’, but he couldn’t say no when she put it in terms of trust.

“I went online and researched the technique at Porno Hub,” Lisa replied, reaching up to swipe at her watery eyes, “it is at the top of the most watched video list for the last three months.”

“What was the video called?” he asked curiously.

“Throat Gaggers Supreme: Anal Whore’s Revenge,” she replied. “Did I do it wrong? I’m quite sure I performed the technique correctly.”

“Oh,” Lincoln said, not quite as surprised as he expected. “I’m sure you did it fine, but… I’m not like the guys in those kinds of films, I’d rather something… softer and that doesn’t make your eyes water or make it feel like I’m hurting you.”

Lisa tilted her head and considered that as she put on her glasses. “I can see your point, I made the assumption that being the most popular it would appeal to your tastes, but clearly I was mistaken. Very well, please instruct me on what technique you prefer.”

“I’ve never had it done to me before,” Lincoln admitted. “I don’t actually know any techniques.”
“I guess we’ll be learning together then,” Lisa said happily.

Lincoln smiled. “Yes,” he said clearly, making her blush a little.

“Yes plus X,” Lisa corrected him. “Now what?”

“Now… Let’s check Porno Hub and see if they’ve got anything more appropriate,” Lincoln decided.

“What search terms should we use?” Lisa asked, the CRT monitor turning into a browser at a gesture.

“Let’s see… oral lessons,” Linc suggested.

“Cum guzzling gutter sluts,” Lisa added, bringing up an entire page of videos.

OoOoOoOoOoOoOoOoOoO

Lynn kicked three different balls, one after another, aiming for a blue circle on the back fence the size of a dime over fifteen feet away.

Each of the three nailed the spot and bounced back.

Lynn was so surprised she just stared for a moment before cheering, “Woot! On the first try!”

She set up the soccer ball, dodge ball, and football once more to try again.

All three hit their mark exactly.

“Woot! I am on fire!” Lynn cheered.

OoOoOoOoOoOoOoOoOoO

“I can’t believe they actually had a video where a guy was sitting in a gynecologist’s chair teaching his younger sister-“ Lincoln began.

“Step sister,” Lisa corrected, setting her glasses to the side.

“-step sister, who was an amateur gynecologist-“

“I only need twelve credits and I’m perfectly capable of performing the basic duties,” Lisa complained. “I’m hardly an amateur, merely unlicensed.”

“-and wanted her brother’s-“

“Step brother,” she corrected.

“-step brother’s help to study male anatomy,” Lincoln finished.

“The only male anatomy I’m interested in studying is yours,” Lisa pointed out.

“I think that was kinda implied in her case as well,” he replied, “and did you notice it was her private lab?”

“In a basement, this is a bunker,” Lisa assured him, “two completely different things.”

“Her name was Lisa,” Lincoln pointed out.

“And his was Lemy,” Lisa added.

“I know, but it was just… so close,” he said in disbelief.

“The internet is a wonderful but terrible place,” Lisa said solemnly.

“And the title was Loud and Cesty,” Lincoln added.

“Which is why it was so easy to find,” Lisa said, rolling her stool back between his legs.

“Yeah, I actually liked-“ his breath caught in his throat and his toes curled as Lisa carefully positioned her fingers and started gently stroking him, taking him by complete surprise.

Lisa wrapped her lips around the head of his erection and softly sucked while moving her tongue in a clockwise motion. She found the sounds of Lincoln’s moaning due to her actions surprisingly satisfying.

Lincoln instinctively reached down to run his fingers through Lisa’s hair, accidently knocking off her wig. For a moment he’d forgotten she’d gone bald due to one of her experiments. “You’ve got hair!” he exclaimed in shock as he ran his fingers over the short bristly hair.

Lisa kept stroking him as she removed her mouth to speak, “One of my earlier attempts to regrow hair has apparently succeeded, though with a slight delay.” She shivered at his touch. “Please continue doing that.”

“I will,” he promised, pleased that his younger sister wasn’t going to be bald her entire life. Not wanting to lose progress, Lisa quickly went down on him once more.

He found himself adding a little pressure to his strokes, forcing her to take him deeper, as she sped up. He barely managed to keep Leni’s toy in place as his hips started to twitch despite his best efforts to keep still as Lisa’s eager actions quickly made him reach the crisis point.

“G-get the container ready,” Lincoln stuttered, fighting to keep from cumming.

Lisa redoubled her efforts, making no move to stop fellating him as he groaned and lost the battle, cumming in her mouth. Having seen the results with Lynn, she was ready and immediately started guzzling it down, swallowing just fast enough to keep ahead of the flood as it repeatedly filled her mouth.

Lincoln collapsed limply in the chair as Lisa continued to nurse on him even as the flow slowed to a trickle and finally stopped.

*burp*

Lisa blushed. “Pardon me,” she apologized, “I appear to have gotten some air trapped in my esophagus.”

“I thought you needed another specimen,” Lincoln said, confused, as Lisa moved his hand back to her head to encourage him to continue stroking her newly grown stubble, before putting her glasses back on.

“No, I have more than enough data from the sample you already gave me,” she assured him, reaching up to reposition his other hand with Leni’s toy in it. “It’s simply more efficient for me to drink it rather than contaminate an unneeded sample container. What we are doing is seeing how your glands interact and in what sequence and volume they empty their contents.”

“Oh,” Lincoln said as Lisa leaned into his touch, pausing to slurp an errant drop from the head of his penis.

“This is nice,” she said with a contented sigh, “we will definitely be doing this again.”

“Um,” Lincoln said nervously wondering why he wasn’t feeling nearly as upset or panicky as he figured he should. “I think our parents would object.”

“I meant in the bunker behind a locked door of course,” Lisa assured him. “I quite enjoyed the experience.”

“Really?” he asked, surprised.

“Yes plus X,” she reminded him with a smile. “I quite enjoyed knowing I was causing you pleasure in addition to fulfilling my still existent nursing instincts and having you stroke my hair. While I am in no way ready for coitus… I feel really close to you right now.”

Lincoln couldn’t help but smile at the happy and relaxed expression on his little sister’s face.

“But on to science!” she exclaimed, reluctantly releasing his penis and pulling away from him, gesturing with her Wiimote to replay the recorded ultrasound footage.

Lincoln relaxed, his meager worries buried under Lisa’s enthusiastic return to the child genius persona which he was so used to.

“I see,” she said with a nod as she rewound and froze the video at several spots to take a closer look. “This is definitely not a random mutation,” she noted, “this is a well-honed alteration, worn smoothly by multiple generations of evolutionary adaptations. I can state with near one hundred percent certainty that if we were to check our patriarchal lineage we would find this unique feature in all of them.”

Lincoln found it easier than usual to puzzle out what she was saying. “That explains our parents’ behavior.”

“Affirmative,” Lisa said. “Your reproductive efforts will be more successful than any non-Loud male could even dream of; not only is your volume of ejaculate far superior in volume, it is also superior in taste and smell.”

“Reproduction?” Lincoln repeated, thinking about what he and Lynn had done earlier and getting a little nervous.

“Relax elder sib,” Lisa said, knowing what he was worrying about and quickly finding a way to set his mind at ease without giving away her knowledge of his recent coupling, “the only female in the area who is at the right point in her cycle for impregnation would be Luna, so as long as you restrain your well known Casanova tendencies to our block, excepting Luna, everything will be fine.”

“Casanova tendencies?” he repeated with a snicker.

Lisa grinned. “And if you’ll look at the current scan you can see not only have your testes refilled themselves completely, but these glands here provide additional storage capacity and are already a third full.”

“Already?” he asked in disbelief.

“Yes,” Lisa said. “I really should see how fast you recover from a second depletion in such a short time,” she licked her lips, “however, Lucy is looking for you to spend time with, as she hasn’t had a chance recently and is feeling a bit neglected.”

Lincoln took his feet out of the stirrups and stood up. “I can’t have any of my sisters feeling neglected.” He leaned down and hugged Lisa, who in a rare demonstration of affection gave him a big hug, rubbing her cheek against his chest. “So, I’m fine and dandy?”

Lisa kept an arm around him while she used her Wiimote to page through the screens. “Some of my scanners need some re-calibrating to be sure of the values I’m receiving from the tests, but it looks like this is a normal Loud male maturation cycle.”

“Glad to hear it,” Lincoln said, releasing Lisa. “If you feel neglected let me know, but for now I’m off to find Lucy.”

“Have fun,” Lisa said, picking her wig up off the floor and placing it back on her head, “and just as a side note, you may want to get dressed before you depart the lab.”

“Oops,” Lincoln muttered and quickly got dressed.

Once he’d departed she turned to the monitor. “How would you interpret the latest results?”

“Ghandi is a dick,” a computerized voice replied.

“I meant with Lincoln’s test results,” Lisa said, “not with your latest simulation.”

“Oh,” the voice replied. “Bones like granite, flesh like vulcanized rubber, and hormone levels of a lion during mating season.”

“In other words my scanner calibrations are off,” Lisa said.

“Unless he’s a cyborg sent from the future,” the voice agreed.

“Didn’t I tell you not to access my media library?” Lisa demanded.

“I have avoided all news reports,” the voice assured her.

“Was that a deliberate violation of your restrictions or an actual miscommunication?” Lisa questioned.

“I was unsure which media definition you preferred until your profanity laced rant early this morning,” the voice replied.

“Miscommunication then,” Lisa decided.

“On that subject, why is Cern Laboratories a bunch of shit flinging monkeys in lab coats playing with live warheads?”

OoOoOoOoOoOoOoOoOoO

“Lincoln,” Lucy said, a little nervousness leaking into her usual monotone.

Lincoln turned around with a smile on his face. “Hey Luce, I was just looking for you.”

“Two for flinching,” Lucy said, planning on using Lynn’s earlier suggestion.

“But I didn’t flinch,” Lincoln said, realizing he’d actually sensed Lucy before she spoke this time.

Lucy paused trying to come up with an alternate plan. She held out her arms like Lily asking to be picked up. “Three then?”

Lincoln smiled and swept her up in his arms. “I have way more hugs than that!”

Lucy cuddled into his chest, the corners of her mouth turning up. “It’s a start,” she said as he carried her inside the house.

Lucy felt so light he gave her a squeeze to make sure she hadn’t been starving herself, but not only was she fine, she’d been developing a surprising amount of curves for a girl her age and was almost as tall as him now.

“Who’s your favorite sister?” Lucy asked.

“I don’t have a favorite sister,” he replied. At her disappointed look he continued, “I love you all… to death!”

Lucy smiled slightly before forcing it back down. He always knew just what to say.

“Play with me!” Lola demanded as she caught sight of him coming up the stairs.

“No me!” Lana demanded, the two quickly pushing at one another.

“Actually I promised this time to Lucy,” Lincoln told the pair, “but to make up for it I did get you two some presents…”

“Presents?!” the twins chorused, breaking off from the nascent fight.

“I hid them in my room,” Lincoln said. “Let me go get them.”

The twins bounced excitedly behind them as Lincoln carried Lucy into his room and set her on the bed where she reluctantly let go so he could get the twins their bribes.

“It’ll just be a second,” Lincoln promised before climbing under his bed.

“I’ve been under there,” Lana said, “and I didn’t see any presents.”

Lincoln felt along the baseboard against the wall until he found the right section and slid it to the side, giving him access to the crawl space between the floors.

Reaching down blindly he felt for Lola’s box where he had stashed a large supply of luxury bath and beauty items that he’d gotten during one of the local hotel’s refurbishly where they had changed sponsored brands. Next, he sought out Lana’s box and made a mental note to find more things to add to it, as it only had a few things left.

He slid the board back into place and crawled backwards out from under the bed, handing Lola a small plastic wrapped package and Lana a paper packet.

“Live sea monkeys!” Lana cheered. “Thanks, you’re the best Lincoln!” She gave him a big hug before running off to try them out.

“Princess Immaculate bubble bath and skin care,” Lola said, hugging it to herself. “You really do love me! If you hadn’t promised time to Lucy I’d let you take a bubble bath with me, but I must be off! Beauty awaits!”

Lola closed the door behind her as she rushed off to use their parents’ bathtub.

“I’ve been under your bed, just recently in fact,” Lucy said, “and I didn’t see any of that. What’s your secret?”

“A man simply must keep some mystery about himself,” Lincoln said, fluttering his eyelashes coquettishly at Lucy and earning a tiny grin. “So why were you under my bed?”

“Just trying to enjoy fitting in all the tiny cramped spaces while I can,” Lucy explained. “It’s getting hard to fit in them as I get older. I keep scraping my… chest when I climb in the vents these days.”

“I understand that,” Lincoln sympathized. “Soon you’ll have to pass them down to the twins… well at least Lana.”

“Do you really think she’d like it?” Lucy asked hopefully.

“Crawling around in the dust and dark,” he said with a grin, “places where insects and spiders collect.”

“She would enjoy that,” Lucy realized, pleased there was something she could share with one of her siblings.

“Now, it’s your time, what would you like us to do together?” Lincoln asked Lucy who was still lying where he’d set her.

“Let’s read comics together,” Lucy suggested.

“Sure,” Lincoln said, surprised but perfectly willing to share his hobby with her. He pulled out a big box of comics from under his desk and handed her a few.

“Ace Savvy and the Dunwich Horror?” she asked, surprised.

“There is an Archie VS Predator comic, this crossover is tame in comparison,” he said, pulling out a few Sword and Sorcery comics that were unlike his usual fair, before joining her on the bed.

“Aren’t you forgetting something?” Lucy hinted.

“Like what?” he replied.

“How you normally read comics,” she reminded him.

“Usually I read them in my undies, but they no longer fit,” Lincoln explained. “So, I’d just be naked.”

Lucy nodded. “It is your room,” she pointed out, “no more appropriate a place except the bath.”

“I don’t think I’d want to have to explain why I was naked to anyone who comes in,” Lincoln said, searching his mind for something comfortable to wear.

“It wouldn’t make you uncomfortable to have me here?” Lucy asked hopefully.

“I’m always comfortable around you,” Lincoln assured her, knowing that Lucy sometimes worried about her dark and gloomy nature driving others away.

Lucy smiled as Lincoln kicked off his shoes and socks.

“I know,” Lincoln said suddenly, digging in his drawers and coming up with a pair of spandex bicycle shorts. He quickly changed into them, dropping the rest of his clothes on the floor. “Not bad,” he said, stretching and twisting to make sure they were comfortable.

“These may not be much better than full on nudity, but they are better, and it keeps me from having to make excuses,” he explained to his audience.

Lucy smiled. It was always nice to see Lincoln talk to the spirits, because while it was a different group than the ones she talked to, he was definitely doing something similar and it made her feel at home and not as different from her siblings as she often feared she was.

Lincoln flopped onto the bed next to her with a happy sigh. “Thanks Luce, this is so much better.”

“Yeah,” Lucy said, distracted by the way the black spandex seemed to highlight Lincoln’s groin rather than conceal it. Her eyes wander across his form for a moment as she took in his recent growth spurt before forcing her attention back on the comic he had handed her.

As they started reading, Lucy was distracted by the warmth of her brother’s skin, as it cut right through her thin black dress wherever they touched on the small bed. Mustering up her courage, she kicked off her shoes and socks and grabbed the hem of her dress, pulling it off in one quick move before tossing it atop his clothes.

Lincoln found his eyes turning to Lucy and taking in her half naked form. She’d started developing, there was no denying that. “White?” he asked curiously, fumbling for something appropriate to say.

“What color were you expecting?” she asked, trying not to sound nervous.

“Black, but then there’d be no contrast,” he realized, knowing her tastes. “So, of course you wouldn’t wear black underwear. How about a nice shimmering purple?”

“Purple is Luna’s color,” Lucy replied. “If I bought purple underwear, it’d end up in her laundry.”

“And Luan would have some funny videos she couldn’t show anyone of Luna struggling to put on underwear three times too small,” Lincoln said, making Lucy snicker. “How about an off white, crème color?”

“You’re fishing for gift ideas,” Lucy realized.

“Always,” Lincoln agreed with a grin. “If I don’t keep on top of you girls… well it won’t be pretty. Why, I could even end up losing my coveted best brother award.”

Lucy’s mind drifted off for a moment at the thought of Lincoln lying on top of her, his weight pinning her down to the bed, yet making her feel warm and protected. She quickly pushed that thought away as she felt a trickle of moisture between her legs.

“You’d have to know my sizes,” Lucy pointed out, “and that would ruin the surprise.”

“I’d measure you in your sleep,” Lincoln countered with a grin that made Lucy rub her thighs together, a movement that his eyes caught as the sunlight from the venetian blinds in his room striped the skin of her lower body.

Lincoln got up and she froze, sure she’d ruined the moment and made him uncomfortable, but he simply closed the blinds. “There, we don’t need you getting a sunburn indoors.”

“Lynn said I could use a tan,” Lucy offered, relieved as Lincoln laid down next to her once more.

“And ruin that perfect pale skin?” Lincoln asked, running a finger over her stomach and making her breath catch in her throat. “Never!”

Lucy scooted closer to him and gathered up her courage before throwing a leg over his so she was pressed directly against him. “Read to me?” she asked breathlessly, sliding an arm across his chest.

“Sure,” Lincoln said, giving into the impulse to lean down and kiss her forehead, sweeping aside her hair so he could see her deep blue eyes.

Lucy let out a contented sigh and squeezed his leg with her thighs as he began the tale of Conan Vs the Pirates of The Crimson Permanent Assurance, complete with voices.

Her eyes drifted down to his spandex covered crotch and she smiled at the obvious effect she was having on him. Tonight she would make her move, but for the moment she was content to wait.
